Summary
New polymers with switchable boron chromophores exhibit multicolor fluorescence dependent on polymerization degree. This allows for tunable emission colors and potential white-light generation in materials.
Area of Science:
- Polymer Chemistry
- Materials Science
- Photophysics
Background:
- Multicolor emissive and responsive materials are crucial for advanced applications.
- Polymers offer excellent processability and stability for material development.
- Switchable boron chromophores present opportunities for novel optical properties.
Purpose of the Study:
- To synthesize and characterize new polymers with switchable boron chromophores.
- To investigate the relationship between polymer properties and multicolor fluorescence.
- To achieve tunable emission colors, including white-light generation.
Main Methods:
- Synthesis of methacrylate monomers containing switchable boron chromophores.
- Polymerization to form homopolymers and copolymers.
- Characterization of photophysical properties, including fluorescence emission.
- Tuning of molecular weight and copolymer composition.
Main Results:
- Homopolymers display multicolor fluorescence dependent on the degree of polymerization (DP).
- Increasing DP shifts emission from blue (tricoordinate boron) to red (tetracoordinate boron).
- Polymers exhibit temperature- and solvent-dependent emission color changes.
- White-light emission achieved by tuning molecular weight or copolymer composition.
Conclusions:
- Developed novel polymers with switchable boron chromophores exhibiting tunable multicolor fluorescence.
- Demonstrated control over emission color through polymer architecture and composition.
- Opened possibilities for creating advanced responsive materials and white-light emitters.

Brønsted-Lowry acid-base chemistry is the transfer of protons; thus, logic suggests a relation between the relative strengths of conjugate acid-base pairs. The strength of an acid or base is quantified in its ionization constant, Ka or Kb, which represents the extent of the acid or base ionization reaction. For the conjugate acid-base pair HA / A−, the ionization equilibrium equations and ionization constant expressions are

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the...

02:39Emission Spectra
76.3K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
